Speed Change Gear Module

Overview of speed change gear module

A speed change gear module is used to change the input speed from the main shaft/auxiliary shaft/composite auxiliary shaft
gear during operation. When not using a speed change gear module, set "0: No speed change gear" in "[Pr.434] Speed
change gear".
With speed change from a speed change gear module, operation is executed with linear acceleration/deceleration based on
the setting for the speed change gear smoothing time constant.
